Burdy - I have a Compaq F572 notebook (AMD athlon x64, nVidia chipset as well) and I had the same issue.
(I'm not at the laptop right now, so I can't reproduce the exact syntax of the dialog...)
When I tried to re-install the device driver, I chose 'Let me choose a location' and then had the installer browse the entire C: drive... it found and installed the Vista drivers for the nVidia on-board video chipset co-processor, and now all is well. (Why it didn't find them in the first place, during install is another question, entirely...)
I hope you have the same results that I had - good luck !
